potential of rainwater
The above table illustrate the potential of rainwater harvesting. You can calculate your potential contribution towards saving the treated water from being wasted for inappropriate use such as toilet flushing, gardening etc.
Use this simple formula to calculate your potential contribution;
Area of your roof (50 sq.m) = Annual rainfal average (litres) of your area x runoff coeficient typically 0.6 , this will give you total volume in litres.
Everyone should get started with rainwater harvesting and contribute by eliminating the act of wasteful by using treated water for inappropriate usage. let us know your situation through email to greenghaz@gmail.com .
